MEANS FOR SOLDERING SEAMS.

To all 'who m. it 1n (1y concern:

Be it known that I, Mounts Kain, a citizen of the United States, and resident of lassaic, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Means for Solderin Seams, of which the following is a specification.

The'object of this invention is to provide sim lo and ctlicient means capable of readily sol ering seams on articles, such as tubes and spouts and other hollow or tubular articles, and also capable of soldering caps or other parts to tubes,spouts and the like.

My improvements enable the seam of a tube or spout and the seam between the tube or spout anda cap to be soldered at one operation, and excess solder that might accumulate u on the soldered parts may be blown away an the parts cooled at one o eration. Spouts or nozzles for cans and ot or containers are frequently made of sheet metal in tapering form, with a screw cap at the larger end and soldering of the seam, and also soldering of the spout and cap together is frequently done by hand operation, but that is costlyand not always accurate. The same may be carried out in my machine expeditiously and accurately.

My invention comprises novel details of improvement that will be more fully hereinatter set fort-hand then pointed out in the claims.

Reference is to ing drawings forming part hereof, wherein,

Figure 1 l8 a plan view of a soldering machine embodying my invention; Fig. 2 is a side elevation, partly in section; Fig. 3 is an end view of the spout gripper, looking from the left in'Fig. 2; Fig. 4 is an enlarged detail section,'illust-rating the spout being gripped, and Fig. 5 --1s a detail section through the valve mechanism on the line 5, 5, in Fig. 1.

Similar numerals of referenceindicate corresponding arts in the several views.

At 1 is a pipe for su iijplying air-under pressure from any suita e source, which pipe is shown securedupon a table or the ike 2. Said'pIpe is provided with a valve 3 having 'a rocking stem 3, to which a coupling 4 is shown secured, a pipe-5 being'secured to said cou ling. Valve 3 is mounts to rotate, for wliieh purpose a tube 6 is attached to the lower part of said Specification of Letters Patent. Application tiled April 2, 1912.

valve and suitably journaled in a coupling 7 at the upper end of pipe 1. The arrangement of port 3 of stem 3 is such that when pipe 5 IS in a lowered position the flow of air through said pipe will be cut oil (see Fig. 5), but when said pipe is raised to an elevated position, the port 3 will register with tube 6 and thus permit the flow of air from tube 6 throu 11 pipe 5. Pipe 6 is shown provided witi an extension (1 havim a counter weight b. Pipe 5 is provided wit 1 a head 5" having any desired number of outlets or nozzles 5 in communication with ipe 5.

At 8 are grippers or fingers having their lower ends opposed to the respective outlets 5 and pivota ly supported upon head 5", as b the shaft 9, so that all of said grippers or ngers may be operated simultaneously. The grippers or fingers 8 are connected with a bar or the like 10, as by the rivets or the like 11, which bar is shown connected by rod 12 with a rock arm 13 pivotally supported upon pipe 5 at 14. A spring 15 serves normally to cause the grippers or fingers 8 to be pressed toward the outlets 5.

At 16 is a tank or bath of soldering ilux or acid 17. Over said tank is a rest 18 for the articles such as tubes or spouts 19 that are to be so dered. Said rest is shown in the form of a plate having slots 18 through which the tubes or spouts pass into the soldering flux.

At 18 are inclined chutes, the lower ends of which terminate over the tubes, spouts or the like that are placed in the chutes 18" will slide down into said slots and de end from plate 18 into the flux.

An uprig t 23 extending from table 2 is shown located in'p'osition to limit. side swing of pi e 5 so that its outlets 5 will be properly rought over the caps 19 to enter the latter. At a suitable distance from the tank 16 1s'a tank to contain molten solder, which may be kept molten by any suitable means, such as by gas burners supplied from gas pipe 21.

At 22 is a articles.

The tubes or spouts 19 shown are of any well known construction and are shown adapted to pass through the screw threaded caps 19 to be soldered to the tubes or spouts, although soldering of the seams of other articles may be accomplished by the marcceiving chute for the soldered the slots 18 so that chinef In the operation of a machine of the example illustrated, an attendant passes the tubes or spouts through the holes in the caps and slides them down the chutes 18 so that they may rest in the slots of the rest 18 see Fig. 2) dipping into the fluid flux. en the articles to besoldered are in such position an'attendant operates lever 13 to cause grippers or fingers 8 to move away from the out .ts 5, and he swings pipe 5 over caps 19" as indicated in Fig. 2, and then releases the grippers which grasp the caps and hold them againstthe outlets. The attendant then raises pipe 5 and carries the attached outlets out of the tank 16, and swings said pipe around over bath 20 and then depresses the articles to be soldered into the molten solder in said bath. The attendant next raises pipe 5 with the attached soldered articles into such position as to cause the ort 3" of valve stem 8" to register with tu e 6 and thereupon air under pressure is blown through pipe 5, nozzles 5 and the attached soldered articles, with the result of blowing from the spouts solder that may have accumulated therein, and also cooling the solder upon the articles. After the tlllflllllS thus been blown through the articles the operator swings pipe 5 downwardly to cut off the air flow, lowers the same over chute 22, and then operates lever 13 to release the soldered articles whichslide down the chute, and the operations stated are repeated.

The dipping of the articles into the molten solder not only solders the seams thereof, but also solders parts of the articles together. If the articles stick at the outlets or rippers, the same may be dislodged by stri ing them against chute22. If .beads of solder collect at the lower ends of the tubes, spouts or the like they may be redipped in the molten bath to cause removal of such beads of solder, and the air blown through toaceomplish the final result.

By means of my inventionit will be understood that several articles may be soldered simultaneously, and excess solder removed therefrom in a simple, accurate and expeditious manner, thereby shortening the time ordinarily required for soldering such articles by hand and'producing properly soldered seams and joints.

Changes may be made in the'details and arrangement of parts set forth, within the scope of the appended claims without departing from the spirit of the invention.
